This is all done from memory, so pardon a possible mistake somewhere in there.
The reason why the /equip commands are after you start casting is because
switching instruments doesn't interrupt casting, and the instrument used to
cast the spell is actually determined 8 seconds after you start casting. This
way, I can have the horn equipped, start casting ballad with Alt-4, and then
press Alt-0 to equip the harp so that when my ballad takes effect, it covers
the whole group. For the higher-level songs, just put II and III after the
name of the spell within the quotes. So when you are using Mage's Ballad II,
the macro becomes /ma "Mage's Ballad II" <me>

Songs
I'll update this with spells costs eventually. Also, keep in mind that by no
means should you have every single spell. It's a good idea to keep Minuet,
Madrigal, Paeon, Ballad, and Lullabies updated though. Magic FFXI Gil is very
important. You only really need Spirited Etude and Learned Etude. Also you
can scrape by with Wind, Ice & Thunder threnodies, but I highly recommend
